Application


Wide range of applications

The SIPROTEC 7SJ602 is a nu-merical overcurrent relaywhich, in addition to its pri-mary use in radial distributionnetworks and motor protec-tion, can also be employed asbackup for feeder, trans-former and generator differ-ential protection.

The SIPROTEC 7SJ602 pro-vides definite-time and in-verse-time overcurrentprotection along with over-load and negative sequenceprotection for a very compre-hensive relay package. In thisway, equipment such as mo-tors can be protected againstasymmetric and excessiveloading. Asymmetric short-circuits with currents that canbe smaller than the largestpossible load currents orphase interruptions are reli-ably detected.

The integrated control func-tion allows simple control of acircuit-breaker or disconnect-or (electrically operated/mo-torized switch) via the inte-grated HMI, DIGSI or SCADA.

Two different housings areavailable. The flush-mountingversion has terminals accessi-ble from the rear. The sur-face-mounting version hasterminals accessible from thefront. Retrofitting of a com-munication module, or re-placement of an existingcommunication module witha new one are both possible.

Construction



Definite-time characteristics

The definite-time overcurrentfunction is based on phase-selective evaluation of thethree phase currents andearth current.

The definite-time overcurrentprotection for the 3 phasecurrents has a low-setovercurrent element (I>), ahigh-set overcurrentelement (I>>) and a high-setinstantaneous element (I>>>).Intentional trip delays can beset from 0 to 60 seconds forthe low-set and high-setovercurrent elements.

The instantaneous zone I>>>trips without any intentionaldelay. The definite-timeovercurrent protection for theearth (ground) current has alow-set overcurrent element(IE>) and a high-setovercurrent element (IE>>).Intentional trip delays can beparameterized from 0 to 60seconds.

Inverse-time chracteristics

In addition, inverse-timeovercurrent protection char-acteristics (IDMTL) can be ac-tivated.

Reset characteristics

For easier time coordinationwith electromechanical relays,reset characteristics accordingto ANSI C37.112 andIEC 60255-3 /BS 142 stan-dards are applied. When usingthe reset characteristic (diskemulation), a reset process isinitiated after the fault cur-rent has disappeared.

Protection FunctionsSIPROTEC 7SJ602 Multifunction Overcurrent and Motor Protection Relay

(Sensitive) directional earth-fault detection(ANSI 64, 67Ns)

The direction of power flow inthe zero sequence is calcu-lated from the zero-sequencecurrent I0 and zero-sequencevoltage V0. For networks withan isolated neutral, the reac-tive current component isevaluated; for compensatednetworks the active currentcomponent or residual resis-tive current is evaluated. Forspecial network conditions,e.g. high-resistance earthednetworks with ohmic-capaci-tive earth-fault current orlow-resistance earthed net-works with ohmic-inductivecurrent, the tripping charac-teristics can be rotated ap-proximately ± 45 degrees(cosine/sinus).

Two modes of earth-fault di-rection detection can be im-plemented: tripping or in“signalling only mode”.

It has the following functions:

� TRIP via the displacementvoltage VE.

� Two instantaneous ele-ments or one instantaneousplus one inverse characteris-tic.

� Each element can be set inforward, reverse, or non-directional.

(Sensitive) earth-faultdetection(ANSI 50Ns, 51Ns / 50N, 51N)

For high-resistance earthednetworks, a sensitive inputtransformer is connected to aphase-balance neutral currenttransformer (also calledcore-balance CT).

Thermal overload protection(ANSI49)

The thermal overload protec-tion function provides trip-ping or alarming based on athermal model calculatedfrom phase currents.

The ambient temperature orthe temperature of the cool-ant can be detected seriallyvia an external temperaturemonitoring box (also calledthermo-box). If there is nothermo-box it is assumed thatthe ambient temperatures areconstant.

Thermal overload protectionwithout preload:

For thermal overload protec-tion without consideration ofthe preload current, the fol-lowing tripping characteristicapplies only when

I � 1.1 · IL

For different thermal timeconstants TL, the trippingtime t is calculated in accor-dance with the followingequation:

Thermal overload protectionwith preload

The thermal overload protec-tion with consideration ofpreload current constantly up-dates the thermal model cal-culation regardless of themagnitude of the phase cur-rents. The tripping time t iscalculated in accordance withthe following tripping charac-teristic (complete memory inaccordance with IEC 60255-8).

Breaker failure protection(ANSI 50BF)

If a faulted portion of theelectrical circuit is not discon-nected upon issuance of a tripcommand, another commandcan be initiated using thebreaker failure protectionwhich operates the circuit-breaker, e.g., of an upstream(higher-level) protection re-lay. Breaker failure is detectedif after a trip command, cur-rent is still flowing in thefaulted circuit. As an option itis possible to make use of thecircuit-breaker position indica-tion.

Negative-sequence protec-tion (I2>>, I2>/ANSI 46 Un-balanced-load protection)

The negative-sequence pro-tection (see Fig. 8) detects aphase failure or load unbal-ance due to network asymme-try. Interruptions, short-circuits or crossedconnections to the currenttransformers are detected.

Furthermore, low level sin-gle-phase and two-phaseshort-circuits (such as faultsbeyond a transformer) as wellas phase interruptions can bedetected.

This function is especially use-ful for motors since negativesequence currents cause im-permissible overheating ofthe rotor.

In order to detect the unbal-anced load, the ratio of nega-tive phase-sequence currentto rated current is evaluated.

I2 = Negative-sequencecurrent

T12 = Tripping time

Transformer protection

The high-set element permitscurrent coordination wherethe overcurrent element func-tions as a backup for thelower-level protection relays,and the overload functionprotects the transformer fromthermal overload. Low-current single-phase faults onthe low voltage side that re-sult in negative phase-se-quence current on the high-voltage side can be detectedwith the negative-sequenceprotection.

Cold load pickup

By means of a binary inputwhich can be wired from amanual close contact, it ispossible to switch theovercurrent pickup settings toless sensitive settings for aprogrammable duration oftime. After the set time hasexpired, the pickup settingsautomatically return to theiroriginal setting. This can com-pensate for initial inrushwhen energizing a circuitwithout compromising thesensitivity of the overcurrentelements during steady stateconditions.

3-pole multishot auto-reclosure(AR, ANSI 79)

Auto-reclosure (AR) enables3-phase auto-reclosing of afeeder which has previouslybeen disconnected by time-overcurrent protection.

Trip circuit supervision(ANSI 74TC)

One or two binary inputs canbe used for the trip circuitmonitoring.

Control

The relay permits circuit-breakers to be opened andclosed without commandfeedback. The circuit-breaker/disconnector may becontrolled by DIGSI, or by theintegrated HMI, or by theLSA/SCADA equipment con-nected to the interface.

Switch-onto-fault protection

If switched onto a fault, in-stantaneous tripping can beeffected. If the internal con-trol function is used (local, viabinary input or via serial inter-face), the manual closingfunction is available withoutany additional wiring. If thecontrol switch is connected toa circuit-breaker by-passingthe internal control function,manual detection using a bi-nary input is implemented.

Busbar protection (Reverseinterlocking)

Binary inputs can be used toblock any of the six currentstages. Parameters are as-signed to decide whether theinput circuit is to operate inopen-circuit or closed-circuitmode. In this case, reverse in-terlocking provides high-speed busbar protection in ra-dial or ring power systemsthat are opened at one point.The reverse interlocking prin-ciple is used, for example, inmedium-voltage power sys-tems and in switchgear forpower plants, where ahigh-voltage system trans-former feeds a busbar sectionwith several medium-voltageoutgoing feeders.

Motor protection

Starting time supervision(ANSI 48)

Starting time supervision pro-tects the motor against longunwanted startups that mightoccur when excessive loadtorque occurs, excessive volt-age drops occur within themotor or if the rotor is locked.Rotor temperature is calcu-lated from measured statorcurrent. The tripping time iscalculated according to thefollowing equation:

Irms = Actual current flow-ing

Restart inhibit (ANSI 66/86)

If a motor is started up toomany times in succession, therotor can be subject to ther-mal overload, especially theupper edges of the bars. Therotor temperature is calcu-lated from the stator currentand the temperature charac-teristic is shown in a sche-matic diagram. The reclosinglockout only permits startup ofthe motor if the rotor has suf-ficient thermal reserves for acomplete start-up.

Undercurrent monitoring(ANSI 37)

With this function, a suddendrop in current, that can occurdue to a reduced motor load,is detected. This can causeshaft breakage, no-load opera-tion of pumps or fan failure.


Temperature monitoring(ANSI 38)

A thermo-box (temperaturemonitoring box) with a totalof 6 measuring sensors can beused for temperature moni-toring and detection by theprotection relay. The thermalstatus of motors, generatorsand transformers can be mon-itored with this device. Addi-tionally, the temperature ofthe bearings of rotating ma-chines are monitored for limitvalue violation. The tempera-tures are being measuredwith the help of temperaturedetectors at various locationsof the device to be protected.

This data is transmitted to theprotection relay via a thermo-box (see “Accessories”).
